NEW Arista DCS-7500R2-18CQ-LC 7500R2 Series 18x 100GB QSFP28 Switch Line Card

The Arista DCS-7500R2-18CQ-LC is an 18-port 100GbE QSFP28 line card for the Arista 7500R series modular switch. Each port runs at wire-rate 100G, and Arista lists the card at up to 18x 100G, 36x 50G, 18x 40G, 72x 25G or 72x 10G, with the higher counts reached through breakout optics or cables.

The card belongs to the 7500R2 generation, which Arista built on the Jericho+ packet processor. With half the port count of the DCS-7500R2-36CQ-LC 36-port 100G line card, it fits slots that need fewer 100G ports.

Arista lists 7500R line cards as supported in the 7504R, 7508R, 7512R and 7516R chassis and in the earlier DCS-7504 and DCS-7508 chassis. For full per-slot bandwidth, pair the card with 7500R fabric, such as the DCS-7504R-FM 7504 fabric module. Arista notes that 7500R2 cards also run on 7500E fabric, at up to 2.2 Tbps per slot instead of 4.8 Tbps, and that 7500E and 7500R fabric modules cannot be mixed in one chassis. Arista recommends the DCS-7500-SUP2 Supervisor-2 module when four or more 7500R line cards are installed. The QSFP28 ports accept 100G optics such as the QSFP-100G-SR4 and also take 40G QSFP+ modules.

This DCS-7500R2-18CQ-LC line card is new and covered by the NetworkTigers one-year warranty. The original packaging may have been opened to inspect the contents.
